I put ammonia for the second but not HCL :/


As did I
Didn't think that paper was too bad, a lot of stuff had came up in a lot of past papers before, calculations were a bit poor though. Believe I got -120 for the enthalpy diagram. 1 for the question with H20, 2 for the value of Y but the others were pretty hard.
I BANGED ANOTHER 120 UMS
i FINISHED THE PAPER IN 15 MINS
What did y'all put for the freezing point of the CaCl2 solution?
